CLOSURE ron RECIPIENTS.

-Application. filed April 21, 1926. Serial No. 103,589.31

The present invention relates to improvements in a hermetic closure for recipients such as glasses, cups, and the like, which will hereinafter be fully described and claimed and is illustrated in the accompanving drawings, in whichz- Figure 1 is a side elevation of a recipient pro... led with a cover and hermetic resilient seal.

Figure 2 is a vertical sectional view through Figure 1.

Figure 3 is a side elevation of a recipient provided with a cover of modified form and hermetic resilientseal.

Figure A} is a vertical sectional view through Figure 3.

Figure 5 is a perspective view of the resilient seal. r

Like numerals of reference indicate corresponding parts in each figure.

The main object of the present invention is to provide a uniform closure for. recipients, which will fit, for instance, allglasses of supposedly the same diameter. It is a well known fact that in drinking glasses,

particularly those of the blown type,

that their opening or mouth will. vary in diameter, according to the amount of contraction or expansion when cooling. It is therefore necessary that the cover should 7 be of such a diameter, that it may readily fit all glasses of a same lot. In some instances, more or less space between the flanged cover and the outer walls of the recipirmt will be provided, which is readily closed by an elastic band. -Supposing that the diameter of the glasses were alike. cerain types of glasses have oblique walls, in which case, a space is also provided, which will also be closed by the said elastic band.

Another object of the present invention is to allow for the expulsion of the air contained in the container after it has been;

sealed, and this cannot readily be done, by

any other means than that described here inafter. When the recipient has been filled with food or otherwise, the coveris placed upon the open end of the container and the elastic band is then placed in position. Innnediately afterwards, the said elastic band may be slightly lifted from the container, for a fewsec onds, and the container is turned upside down, to force the air through the space provided between the wall of the recipient and the flange on the cover, outside of said container, and to establish a partial Yvacuum therein, afterwhich the elastic band is placed back into position, to provide an airtight, leak-proof closure.

Referring to the drawings, 1 is a recipicut and illustrated in the drawings, as a glass, the walls 2 of which are oblique, and 3 s a 'coverofpreferably slightly larger diameterthan that of the recipient having a perpendicular circumferential flange 4 adapted to project downwardly, whereby a space 5 is provided. between the upper oblique edge of the recipient 1 and the inner side of the flange 4.

Over the said flange 4 is placed aflat elastic band 6 which projects downwardly in the form of a skirt from said flange and engages the outer wall of the recipient which closes hermetically the space 5 and simultaneously secures the cover to the saidrecipient. The space5 provided between theflangc i and the wall of the recipient permits theband to be lifted out of contact with the container wall when it is desired to expel air from; the interior of said container during the preserving operation. The preserving operation having been completed, the elastic band tightly engages the edge of the cover and the container walls to form a hermetic seal for the recipient.

This feature may be improved by providing a head 7 on the lower edge of the flange 4, in case the walls of the recipient are not at such a pronounced angle, as shown .in Figures 3 and 4. This bead has also the advantage of securing the band 6 on the flange and thus preventing the said band from slipping.

The flat elastic band 6 is preferably of relatively smalier diameter than that of the recipient, so that it should be extended when placing it over the cover, in order that a staunch and hermetic seal be provided. The said band is independent from the cover, so that when it is desired to open the container the said band is readily removed from the cover and the said cover may then be used to close the recipient without the use of the said elastic band.

What I claim as my invention is 1. A closure for recipients, consisting of a cover of slightly larger diameter than the open end of said recipient, said cover having a circumferential depending flange which extends beyond the walls ofsaid recipient at a suitable distance therefrom,

whereby a space is provided therehetween, and a fiat elastic band adapted to engage said flange and the walls of said recipi it, whereby said elastic band may be Lily lifted from the outer Walls of said recipient, for the purpose of aiding the escape of air from the interior of the container.

2. A closure for recipients having eblique walls, comprising a cover provided with a circumferential depending flange which extends beyond the Walls of said recipient,

whereby a space is provided therehetween, and .a flat elastic band adapted to engage flange and the Walls of said recipient, whereby said elastic band may be readily lifted from the outer Walls of the said recipient, for ,the purpose of aiding the escape of air from the interior of the container.
